OK, I will look some time this week ...

Hmmm ...

OK, I doubt that it is you programming skills. The problem may be that in
libsmbclient, when you open a directory, I slurp up all the entries in the
directory into malloc'd structures ...

This is forced on my because I re-used a lower layer libsmb routine that
expected to read the whole directory in one go and calls a call-back ...

Perhaps I need to defer reading the directory until smbc_getdents is
called. I was wondering when this would bite, and perhaps it is now ...
